以下是引用zhuzhu1973在2004-9-14 1:51:00的发言：

7.Duck have been domesticated for many centuries____ commercially for their meet and eggs.

A.raised.

B.and are raised.

C.raised as

D.are raised.

答案:B. A为什么错,过去分词作状语也说得通呀.是不是centuries后面有一逗号的话,A就对了?

逗号的作用可太微妙了，确实是，有逗号Ａ才说的过去．

8. According to the fossil record of carnivore families, felines developed more rapidly than ___

A. other carnivore families were

B.other carnivore families

C. there were other cannivore families.

D. so did other canivore families.

B对没错.但D好象也可以啊.

ＴＨＡＮ后直接跟比较的对象，Ｄ成了平行对比了，并没比较呀

9. Computer graphics are ___ programmed and operated by human beings.

A.the computer generates pictures.

B.computers generated pictures.

C. pictures generate computers

D pictures generated by a computer.

答案应该是D吧?

谢谢.

第八题还是有点问题是否等同于other canivore families developed rapidly. so 代替 rapidly,所以多余.

zhoushao

so did other canivore families.是倒装结构，other canivore families developed rapidlyＪＪ说的是对的，只是ＴＨＡＮ后用倒装挺怪的，结构也应是other canivore families　did,不用ＳＯ代替．
